Specific batches of products are being recalled by the Marketing Authorisation Holders and parallel distributor companies as a precautionary measure due to contamination with an impurity called 5-(4’-(azidomethyl)-[1,1’-biphenyl]-2yl)-1H-tetrazole, which has mutagenic potential. These batches are being recalled as the level of contamination is above the acceptable limit.
Further information including details of the affected products and batches, a brief description of the problem and advice for healthcare professionals can be found on the MHRA website.
